Interactive Keys (Free Choice)These keys allow the user to select which features of a plant to use for identification and in what order to use them. Our keys have been developed with the user in mind. They were created using Lucid, a program made by the Centre for Biological Information Technology (CBIT) at the University of Queensland. Please view our video tutorial for a better understanding of how the keys work.
 
Interactive Dichotomous Keys (Directed Choice)These keys require the user to give information on features selected by the author of the key and in the order selected by the author. They were created using Phoenix, another program made by CBIT. The resulting keys are more flexible than printed keys because they allow users to skip leads, returning to the skipped leads later, if desired.
